Mihai Budiu updated CALCITE-6324: --------------------------------- Fix Version/s: 1.37.0 > Type inferred for result of STDDEV, VAR_SAMP, etc. is incorrect > --------------------------------------------------------------- > > Key: CALCITE-6324 > URL: https://issues.apache.org/jira/browse/CALCITE-6324 > Project: Calcite > Issue Type: Bug > Components: core > Affects Versions: 1.36.0 > Reporter: Mihai Budiu > Assignee: Mihai Budiu > Priority: Minor > Labels: pull-request-available > Fix For: 1.37.0 > > > These functions are all use the same type inference algorithm, essentially > the algorithm used by AVG. > But if the values processed are decimal, STDDEV (and others) need much higher > precision to represent the result. (I am not sure that the inference is right > for integer types either, btw.) > This surfaced during the implementation of a fix for [CALCITE-6322]: if we > use the type inferred for these functions, the result overflows and causes a > runtime exception. -- This message was sent by Atlassian Jira (v8.20.10#820010)
